The housing 2 comprises a pair of side walls 21, a bottom wall 22, a top wall 23, a plug-receiving cavity 24 defined therebetween. One of the side wall 21 defines a rectangular hole 211. Each side wall 21 includes a bolt 212 extending rearwardly from a rear end thereof for connecting a printed circuit board (not shown). The bottom wall 22 defines a rectangular receiving groove 221 in a front portion thereof and a pair of rectangular holes 222 therethrough in a rear portion thereof.
The terminal-receiving part 3, made from insulative material, is received in the housing 2. The terminal-receiving part 3 receives a pair of terminals 4. The terminal-receiving part 3 includes a base portion 31, a side portion 32 extending rearwardly from one side of the base portion 31, a horizontal portion 33 extending forwardly from a bottom portion of the base portion 31, a top portion 34 extending upwardly from the base portion 31 and a pair of legs 35 extending backwardly from a bottom portion of the base portion 31. The base portion 31 has a front face 311 supporting free ends of contact portions (will be described later) of the terminals 4. The side portion 32 includes a top wall 321, a side wall 322, a bottom wall 323, and a leading-wire space 324 defined therebetween. The leading-wire space 324 communicates with the hole 211 of the housing 2. The top wall 321 defines a leading-wire notch 325 communicating with the leading-wire space 324. The horizontal portion 33 defines a pair of slits 312. The top portion 34 defines a pair of through apertures 341 extending vertically, a pair of leading-wire cutouts 342 extending substantially rearwardly from top ends of the apertures 341 and a pair of protruding portions 343 extending upwardly from opposite sides thereof. Rear openings of the leading-wire cutouts 342 are corresponding to a front portion of the leading-wire notch 325. Each leg 35 comprises a latch 351 extending downwardly from a free end thereof.
The terminals 4 are received in the terminal-receiving part 3. Each terminal includes a leading-wire end 41 connecting a wire 344 and a contact portion 42 electrically connecting to a mating plug (not shown). Each leading-wire end 41 extends upwardly from a top portion of each aperture 341 respectively. A vertical portion (no labeled) of each terminal 4 is respectively received in the apertures 341 of the terminal-receiving part 3, and a horizontal portion (no labeled) of each terminal 4 is respectively received in the slits 312 of the terminal-receiving part 3.
The metal shell 5, made of a metal sheet, covers the insulative housing 2. The metal shell 5 includes a pair of side walls 51 each having a rectangular hole 511 aligning with the hole 211 of the insulative housing 2. Each side wall 51 comprises a grounding footer 512 extending backwardly from a rear end thereof.
Referring to FIGS. 1, 2, 3 and 4, in assembling, firstly, the terminals 4 are mounted into the terminal-receiving part 3, and wires 344 are connected to the leading-wire ends 41 of the terminals 4. The wires 344 passes the leading-wire cutouts 342, then through the leading-wire notch 325, finally extending into the leading-wire space 324. Secondly, the terminal-receiving part 3 is inserted into a rear portion of the housing 2. The horizontal portion 33 is received in the receiving groove 221. Each latch 351 of the legs 35 is respectively secured in the holes 222. The protruding portions 343 attaches to an inner surface of the top wall 23 of the insulative housing 2. The leading-wire space 324 communicates with the hole 211 of the insulative housing 2. The wires 344 extends out of the hole 211 of the insulative housing 2 from the leading-wire space 324. Finally, the shell 5 covers the insulative housing 2. The holes 511 communicates with the holes 211, so that the wires 344 extends out of a side portion of the modular jack 100.
